Muscle plasty in surgical treatment of congenital dislocation of the hip in children

Abstract

Active development of extra-articular, low-traumatic methods of surgical treatment of congenital dislocation of the femur has reduced the number of such postoperative complications as relaxation, decentration, and aseptic necrosis of the femoral head by now. As a rule, the main focus of research is on surgeries with correction of the pelvic and femoral components. But it is not uncommon that even correctly performed open reduction of congenital dislocation of the femur and restoration of proper coaptation of the articular surfaces end in failure. Lateroposition, decentration, or even reluxation occur either immediately after removal of the plaster immobilization or in the course of active physical and mechanical therapy. One of the main reasons for such failures is the imbalance between the internal and external rotators of the femur that occurs after correction of the anteversion angle.
